Toa/ZZ whom it may con/cern:

Be it` known that I, ISAAC N. HAGUE, a citizen of the United States, residingl at 3414 PacificlV avenue, in thecity of Tacoma, in the county of*` Pierce and; State of Washington,

have invented? certain new and useful Improvementsin Gang Saw- Ed ging Machines; of` whichithe following is a specification.

My invention pertains to certain new and useful improvements in gang-saw-edging machines commonly used in lumber saw-mills and manufactories. f

The object of my invention is to provide an automatic shield thatwillprote'ct the operatorfrom flying fragments and splint-ers cut fromthe edge ofthe board or plank passing through the edging-machine and hurled back by the edging-sawstoward the operator. I attain this obj ect by; means ofthe mechanism illustrated in the accompanying drawings, in which- Figure l is a vertical section through a gang-saw-edging machine, showing the application and operation of my invention. Fig. 2 is a top view of a gang-saw-edging machine with my invention in place thereon.

Similar letters refer to similar parts in both the views.

Previous to my invention gang -sawedging machines have been operated with feed-rollers A A and a solid traveler-roller B above each to hold the plank or board (indicated by broken lines) firmly thereon, and thus insure sufficient friction on .the feed-rollers A A to force the same against the edging-saws D. The travelerroller above A, heretofore being one solid roller, was raised up its full length, thus having an open space on each side of the plank equal to the planks thickness.- The material to be edged often consists of feather-edged slabs or planks cut from the sides of the logs, and when being run through the edging-machine sharp-pointed fragments and slivers are often cut loose from the feather edge of the plank and hurled back against the front feed-rollers and frequently through the open space between the rollers at the sides of the plank. `Painful and sometimes fatal accidents have resulted from these iiying fragments or slivers, and to prevent the operators of the machines from being injured I have conceived the idea of def vising a traveler-roller to be used above the front feed-roller A, that will automatically close the gap or opening between the rollers at the sides of the plank, being edged, and thus form ashield to the operator.-

My invention comprises a,l traveler-roller composed of a multiplelof rollers E Ef, each of which is separately and independently mounted directly above the feed-roller A. These traveler-rollers lmay be of suitable lengths each, and their combined lengths are to equal the length of theifeed-roller A below them. Each roller is pivotally mounted at F by a swinging arm G, and each swinging` arm is provi `ed with a lever-armH, on which` is fixed a weightl I. Each swinging armGis suitably forked to receive its traveler-roller E and the ends of the central; shaft J,- on which it revolves. On the loweredgeof each fork is a beak-like extension K to the lower side of therollersE E', which closes thespace between the rollers E E and makes the shield complete.

In operating a gang-saw-edging machine with my improvement attached thereon a plank, as indicated by the broken lines C, is fed into the machine, and only the rollers E, under which it passes, will be raised up, as

lshown on the drawings, while those at the sides, which clear the plank, will remain down,

close to the feed-roller A, as shown, and will safely shield and protect the operator from dangerous fragments and slivers that may be hurled back toward him by the saw. The

rollers clear of the plank are indicated by E.

It will be observed that each weight I is provided with a socket-cushion L, of suitable material, and that this cushion L rests on a cross rod or bar M when its roller is down, and thus prevents each roller from striking and riding hard on the feed-roller A. These cushions may be so adjusted when placed in position that the rollers will clear the roller A. I am aware that traveler presser-rollers in woodworking-machines have heretofore been made with a multiple of roller-sections in the width of the machines, and I do not, therefore, herein make claim to such feature otherwise than as embraced in mechanism constructed and operated as herein specified.

I-Iaving described my invention, what I claim as new and useful, and desire to Secure by Letters Patent, is-,

1. A gang-saw-edging machine, having a front traveler presser-roller, said roller composed of a number of short rollers, each separately mounted on a swinging arm so that one or more of said short rollers will remain. down beside the plank passing through said machine to substantially close the space between 'said presser-rollers and the feed-roll substantially as shown and for the purpose set forth.

2. A gang-saw-edging machine, having an automatic shield comprising a front traveler presser-roller, said presser-roller composed of a number of short rollers, each of said rollers separately mounted on a weighted swinging arm to drop down when off the plank passing through said machine, and each swinging arm provided with a downward extension to close the space between said presser and the feed rollers substantially as shown and for the purpose set forth.

3. In a gang-saw-edging machine, the combination with a gang of saws, of a shield on the feed side of the saws, comprising a number of rollers disposed side by side of each other, above afeed-roller, and in their normal position substantially closing the opening between said shield-rollers and feedroll a swinging arm for each roller, a weighted leverconnected to each arm, and a stop limiting the downward movement of each swinging arm, substantially as described.

4. In a gang-saw-edging machine, the

combination with a gang of saws, and a feedroll in advance thereof, of a shield on the feed side of the saws comprising a number of rollers disposed side by side of each other, above the feed-roll, and a lswingin arm for each roller, said rolls bein adaptedD normally to lie close to the feed-rol? and to conform to the thickness of the board passing between them and the feed-roll, the rolls under which the board does not pass remaining close to the feed-roll to substantially close the space between said shield-rollers and the feed-roll while the others are raised'by the board, substantially as described.

5. In a gan -saw-edging machine, the combination wit a gang of saws, and a feedroll in advance thereof, of a shield on the feed in presence of two witnesses.
